OPC Environment tab

On this tab results returned by callbacks for created and active subscriptions are presented. Each item has its “Item ID” (item text identifier), “Item Path” (path to the item in OPC server address space) ”Value”, “Data Type” (e.g. String, Boolean, Int32, etc.), “Quality” (e.g. good, bad, uncertain, etc.), “Timestamp” (information about when the data was read), “Result” (additional information about errors that comes from OPC communication engine). If everything is OK the result should be: “S_OK”, otherwise the returned result informs about the kind and type of error.

The following example of the OPC panel contains values of three items. All items are Int32, contain the value: “0”, and have good quality.
